MERIT E. IVILSON, OF

GRAIN-DRILL.

Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed November 13,1906. Serial No. 343.219.

To aZZ whom it may concern/.-

Be it known that I, MERIT E. WILSON, a citizen of the United States, residing at Holdenville, in the Western District of Indian Territory, have invented a new and useful Grain-Drill, of which the following is a specification.

This invention has relation to grain-drills and it consists in the novel construction and arrangement of its parts, as hereinafter shown and described.

The object of the invention is to provide a grain-drill comprising beams between which a colter-disk is journaled. The rear ends of the beams are attached to a drill-tube, and a shoe is attached to the lower end of the tube and is provided at its forward end with plates that extend upon opposite sides of the colterdisk and are attached to the beam at points between the journal-bearings of the colterdisk and the drill-tube. The said plates are in close contact with the sides of the colterdisk and serve as scrapers for removing mud from the same.

In the accompanying drawings, Figure 1 is a perspective view of the grain-drill. Fig. 2 is a side elevation of the same, and Fig. 3 is a sectional view out on the line 3 3 of Fig. 2.

The beams 1 1 are adapted to be attached at their forward ends to the frame of the drill. (Not shown.) The colter-disk 2 is journaled between the said beams and is formed, preferably, from a thin piece of sheet metal. drill-tube 3 is secured between the rear ends of the beams 1. The lower end of the said tube is provided with the forwardly-extending wedge-shape lug 4. The grain-shoe 5 is preferably made of sheet metal and is attached to the lower end of the tube 3 and to the sides of the wedge-shape lug 4. The forward portion of the shoe 5 is continued into the plates 6 6, which extend up on opposite sides of the colter-disk 2 and are secured at their upper ends to the beams 1 1 at points between the j ournal-bearing of the disk 2 and the drill-tube 3. The said plates 6 are in close contact with the sides of the disk 2 and serve as scrapers for relieving the said disk of mud. The upper portions of the plates 6 are bent laterally for short sections, and such sections present precipitous walls to the mud The l I removed from the disk and collected upon I ends of the beams l at their points of attachment with the drill-tube 3 to the lower edge of the grain-shoe 5.

J Consequently the said colter-disk 2 will cut deeper in the ground than the lower ed e of the grain-shoe 5. As the parts above escribed are so connected together that they must all move vertically in unison when the colter-wheel 2 strikes a rock or a root, it rides over the same, and the grain-shoe 5 is lifted over such obstruction without being brought in forcible contact With the same. Thus the shoe is relieved of rough usage and preserves its shape and configuration.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a grain-drill supporting-beams, a colter-disk journaled between the beams, a drill-tube fixed to the beams, a grain-shoe attached to the drill-tube and having its forward portion continued into plates which lie vertically along opposite sides of the colterdisk and in contact with the same and which are attached at their upper ends to said i beams.

2. In a grain-drill, supporting-beams, a colter-disk journaled between the beams, a drill-tube secured between the beams, a grain-shoe attached to the lower end of the drill-tube and continued into plates which lie vertically along opposite sides of the colter-disk and are in close contact with the same, the upper portions of said plates having lateral outstanding sections which are attached to the said beams.

In testimony that I claim the foregoing as my own I have hereto afiiXed my signature in the presence of two witnesses.

MERIT E. WILSON.
